3 Claims. (Cl. 36--59) This invention relatesin general to anti-skid shoes and boots designed for walking on ice and 'other slippery surfaces. Normally, anti-skid shoes provided with studs are used for walking on snow, ice, and other slippery surfaces, and ofttimes the snow and ice builds up on the shoe sole to form a hard cake of approximately the same thickness as the projecting studs, thus eliminating the gripping feature which normally prevents slipping or falling when walking on ice. n

One of the prime objects of the invention is to design an anti-skid shoe of simple, practical, and inexpensive construction, the spikes of whichare automatically selfcleaning as the wearer walks.

Another object of the invention is'to provide recessed areas in the shoe soles and heels in which the anti-skid Imeans is resiliently mounted, so that the flexing of the` shoe sole, when the wearer walks,l produces a reciproeating movement of the anti-skid means, as the body weight is shifted from one foot to the other.l This walking movement automatically forces the anti-skid spikes downwardly when the body weight is impressed on the one foot, and the spikes are then retracted a predetermined distance into the sole lof the shoe, when the body weight is transferred to the other foot.

to the opposite foot, so that the spikes are self-cleaning when the body weight is removed from the foot and the resilient means expands, thus providing a pulsating movement of the spikes in the sole of the shoe. v

With the above, and other objects in view, the present invention consists in the combinationrand arrangement of parts, hereinafter and more fully described, illustrated in the accompanying drawing and more particularly pointed out inthe appending claims, it being understood that changes may be made in the form, size, proportion,l and minor details of construction, without departing from the spirit, or sacrificing any of the advantages of the In.the drawing: p Y `FIGURE l is a side elevational view of a shoe show-l ing my novel antiskid means in place thereon.

v 3,170,251 Patented Feb. 23, 1965 ICC spectively, are formed in the upperV face and heel section Vof said anti-skid sole, .the area 12being formed in the heel as shown. Rigid plates P are mounted in the' recesses 11l and 12, and a plurality of spaced apart steel spike members 14 are rigidly mounted on each plate,

. Withfthe free ends of the spikes projecting through openings y1S provided in the anti-skid sole 10, and through similar openings provided in the heel section of the sole.

A resilient pad 16 is glued or otherwise secured to the upper face of each plate P, and forma unit of a size to freely t in the recesses 11 and 12, and it will be noted that the plate P is rigid and the spikes 14 are solidly mounted therein; and in walking, the body weight on the foot and flexing of the shoe when walking compresses the pads 16 and forces the spikes outwardly and downwardly for piercing engagement with the ice. When the body weight is removed, the pads retract and the sole returns to original position, forcing the plate P upwardly and this retracts the spikes into the sole and performs a self-cleaning action at each step` The anti-skid assembly for the heel of the shoe is formed in exactly the same way as that above described, excepting that the plate P has but three spikes arranged in triangular relation (see FIG. 3 of the drawings), otherv wise the construction is exactly the same. The in and Vout travel of the spikes, caused by the act of walking,

which shifts the body weight from one foot to the other, eliminates Vany possibility of building up and packing cakes of ice and snow between the spikes, as such cakes would make the contact on ice more slippery than absence of spikes entirely, as the spikes in such instance would Y serveV to anchor and hold lthe cake around the spikes on the sole.

The anti-skid arrangementV above described is preferable for adults of average or heavy weight. lFor adults of average or heavy weight, the resilient pad is mounted on the underside of the plate P with the spikes projecting FIGURE 2 isa sectional top plan view, the inner Y.

v FIGURE V5jis a view similar to FIGURE 4 `showing the 'resilient pad mountedfon the lower face of the p creeper plate, and usedmofsitlyrby large persons of average orheavy weight. Y

LReferringrnow more particularly to the drawingdn which I havershown the.preferredembodiment of my in- `vention. ,The letter SA indicates 'af conventional shoe to which my anti-skid means'is attached, theV upper body of sages in each recessed area extending through said sole, anti-skid plates movable vertically in said recessed areas through the pad, see FIGS. 3 and..5 of the drawings. With this arrangement, the spikesproject a very limited disance below the outer face of the sole V10, the flexing -of the foot and sole of the shoe exposing the spikes which are then drawn substantially flush with the face of the sole when the weightis shifted to the opposite foot. The heel pad arrangement, shown in FIGS. 3 andV 4 of the drawings, is the same for both children and adults. v

From theV foregoing description, it will be obvious that I have perfected a very simple, practical, and effective anti-skid shoe for walking on lice and'other slippery surfaces.

I claim:

l. An anti-skid shoe lprovided with a sole having recessed areas in the upper face thereof; a pattern of pasand formed with a plurality of sharpened spikes slidable in said passages asl the wearers weight is shifted from one foot to the other; resilient pads secured to said plates;

said spikes 3 having reciprocal? movement in said sole Y passages toy 'clean theV surface of the spikes when the wearer is walking. v

2. An anti-skid'shoe, including a shoe sole; an anti.-

'v skidsole secured to the shoe sole and having a recessed L area in the upper face thereof; a rigid platemountediiny said recessed area and formed witha plurality of sharp-A l-ened spikes on thev lower face, thereof, said spikes projecting a predetermined distance beyond the lower face of the anti-skid sole; a resilient pad glued to the upper face of said plate; said pad normally projecting slightly above the upper face of the recessed sole, and spike passages in said anti-skid sole inalignment with and ac'- commodating said spikes.

3. An anti-skid sole for a shoe provided with a recessed area in the upper face thereof, a plate mounted in the recessed area, a resilient pad glued to thelower face of said plate, a plurality of downwardly projecting spikes on the lower face of said plate and projecting through said pad, said plate being mounted for vertical movement in said recessed area, and openings in the recessed are of the sole for accommodating said spikes.
